High-End Computing Program

Delivering high-end computing systems and services to NASA's aeronautics, exploration, science, and space technology missions.


If you are a NASA-sponsored scientist or engineer, computing time is available to you at the High-End Computing (HEC) Program's NASA Advanced Supercomputing (NAS) Facility and NASA Center for Climate Simulation (NCCS).

01.19.21 - 2020 HEC Needs Assessment Report Now Available
The NASA High-End Comuting (HEC) Needs Assessment report documents the HEC users’ needs raised during a virtual workshop that took place June 1–19, 2020 in terms of computing capacity, technology, services, human resources, and programmatic. The HEC Program will use the information to develop future investment and program implementation strategies.

11.22.21 - New Deep Learning Method Adds 301 Planets to Kepler's Total Count
Scientists recently added a whopping 301 newly validated exoplanets to the total exoplanet tally. They used a new deep neural network called ExoMiner that leverages NASA’s Pleiades supercomputer and can distinguish real exoplanets from different types of imposters, or "false positives."

11.18.21 - NASA’s Newest Supercomputer Gets a Power Boost
NASA’s Aitken supercomputer is being expanded with 512 new nodes that will be available to scientists and engineers across the country on Nov. 19. The boost brings the system’s theoretical peak performance to 10.77 petaflops—a 28% increase in performance, which translates to solving larger problems with faster results for important NASA research projects in aeronautics, human and robotic space missions, Earth science, and astrophysics.
Computer simulation of a potential air taxi stabilization system at work
11.18.21 - NASA Simulates a Smooth Ride to Stabilize Air Taxis
When air taxis begin shuttling us around, the rides they offer will need to be safe and smooth. Sudden gusts of wind could cause a turbulent flight, and NASA is designing a system that will actively stabilize these vehicles. The complex computations needed to simulate this system required the agency’s Pleiades supercomputer.

11.17.21 - Supercomputing Reveals "Fossil Record" of Galaxy Collisions and Mergers
Using the Pleiades supercomputer at the NASA Advanced Supercomputing (NAS) facility and data from the Hubble Space Telescope, researchers simulated a Milky Way-like galaxy in the early stages of a collision with another smaller galaxy—revealing a detailed “fossil record” of information about the simulated galaxy’s history.

11.17.21 - Reducing Emissions to Mitigate Climate Change Could Yield Dramatic Health Benefits by 2030
According to computer model projections run on the NASA Center for Climate Simulation (NCCS) Discover supercomputer and the Duke Compute Cluster, improved air quality caused by reducing emissions from burning fossil fuels and other sources could improve human health and prevent economic losses.

11.12.21 - 6 Things to Know About Supercomputing at NASA
From exploring the solar system and outer space to improving life here on Earth, supercomputing is vital to NASA missions. The agency will host a virtual exhibit to showcase how these powerful machines enable science and engineering advances during the International Conference for High Performance Computing, Networking, Storage and Analysis Nov. 14–19, 2021.
